Abstract

Panicle differences in mean grain length, breadth, thickness, weight, and length were not statistically significant. A significant difference in mean stalk height and days to flowering and maturity was noted between the hybrids and the paternal parent group,

but the means were more inclined toward the maternal parent group. Difference in seedling height between the hybrids and the maternal parent group and between the hybrids and paternal parent group was highly significant at both levels, but the means did not point to intermediateness or hybridity.

Mean root length between the groups was not significantly different; those of the hybrids were insignificantly longer than the longer parent group. Mean hybrid tillers was insignificantly more than the Japonica group and inclined toward it.

In some of the crosses, purple was dominant over green or non- color, non-shattering over shattering, resistance to drought over susceptibility to drought.
